Looking for 2d Tree sprites with a fair amount of detail

Hey there! I'm currently in the middle of making a 2.5D RPG game, and i'm looking for some tree assets that can be used in unity as 2d sprites. Ideally i'd like a bit of animation and they would be free to use on my project. The kind of quality im looking for is exemplified below. I've had a look through the 2d trees on this site and they don't quite fit the asthetic for some reason.

I'd like a few different types of tree if possible, Birch, Oak, Pine etc. and would be willing to discuss an exchange for the cost of the project. If anyone is able to help please let me know! I'm not an artist at all. The tree below is from a free unity asset pack that i'm currently using.
